SAFETY-RAZOR FRAME.

SPECIFICATION forming part of Letters Patent No. 769,114, datednugastao, 1904.

Application filed March 2, 1903. Serial No. 145,776. (No model.)

T all whom, t may concern:

Be it known that I, AUGUs'r WILLIAM Sonno- BER, a citizen of the UnitedStates, residing at Hoboken, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inSafety-Razor Frames or Casings, of which the following is a full, clear,and exact speciiication.

The object of my invention is to provide a 1o casing having as few partsas possible wherein the blade may be readily inserted or removedtherefrom without danger of injuring it; and it consists of thecombinations, parts,

' and improvements hereinafter more fully set I 5 forth, andparticularly pointed out' in the claims. i

It further consists in providing an absolutely rigid support for theblade, no matter how imperfectly or unevenly it may be ground,

2o and the invention provides that the blade automatically adjustsitself in a proper position upon being inserted in the casing.

In the accompanying drawings, illustrating two forms of my invention,Figure 1 is a front z5 perspective view showing the casing and a bladein place therein, and Fig. 2 a side view of the casing complete. Fig. 3is a perspective View of the rear. of the casing; and Fig. t a top viewshowing the'guard-comb, bladesupport, and clips. Fig. is a sectionalview taken on lines m of Fig. 2. Fig. 6 is a side view similar to Fig.2, but showing the lip for holding the blade thrown back and the clipsraised; and Fig. 7 is a sectional view 3'5' taken -on lines y y of Fig.3. Another form of my invention is shown in the second sheet ofdrawings, wherein Fig.' 8 is aside sectional view taken on lines e z ofvFig. 10; Fig. 9, a 'side View; Fig. 10, a top view of the bladeholder,guard-teeth, &c.; Fig. 11, a sidesectional view similar to Fig. 8, butshowing the sliding lip pulled out for the insertion of the blade; Figs.12 and 13, front and top views of` `the spring for operating the variousparts; and Fig. 14 is a perspective view of the sliding lip. Fig. 15 isa detailed view of a portion of the blade-support, hereinafter moreparticularly described.

In the drawings, 1 represents the conventional casing having the handle2, and'to this casing is pivoted, as at 3, the blade-support 4:,provided with the usual guard-teeth 5. To the blade-support and at theends and back thereof is pivoted the clip-frame 6, consisting of thearms 7 7, carrying the clips 8 and the cross-arm 9, having a slightelevation or projection 10 on its upper side at its middle portion. Tothe inner and rear face of the bladesupport is rigidly secured theyoke-shaped spring llt-for instance, by the rivets 12 12H and thisspring serves the following purposes: The ends 13 13 normally pressrearwardly against the lugs or shoulders 14L 14 on the clipframe, andthereby exert a constant tension serving to keep the clips down incontact with the top of the blade-support, as in Fig. 2. The head ofthe` yoke 15 bears against a lug 16 on the end of the lip or finger 17,which finger is pivoted to swing at the back of the blade-support, aswill be readily understood from Fig. 5, and serves to hold the lip ineither of two 'positions -tirst, when swung forward to bear against theback of the blade, and, second, when swung back for the insertion of theblade, as shown vin Fig. 6. The projecting tongue 18 of this spring hasa small projection 19 struck from its surface, which is adapted toengage arecess 20 in the casing, and this acts as a catch which securesthe blade-support to the casing and which can be readily operated by thebuttonk 21, secured to the spring. It is obvious that by pressing onthis button the catch is not only released, but the blade-support isswung open by the same movement. It will likewise be readily -seenthatwhen the lip 17 is sw ung backward for the insertion of the blade itstrikes the elevation '10 of the cross-arm 9 and forces it slightlydownward, thereby raising the clips and permitting a ready insertion ofthe blade as far as the stops or studs 22, but no farther, as the clipsare not raised high enough to permit the blade to be lifted orforcedover the said stops. Upon swinging the lip 17 forward the pressureon the cross arm @is removed and the clipsare forced downward on theface of the blade by means of the spring-arms 13, and the clips bearingagainst the back of the blade .hold it firmly in place against allmovement.

It will thus be seen that a single spring not only governs the clips andthe lip at the back of the blade, but operates the catch holding theblade-support to the casing.

In razors with casings of this type wherein the proper position of theblade is determined by its edge abutting against fixed stops, such as22, considerable danger exists of breaking the edge of the blade atthese points, and this is particularly so where the blade is forcedagainst the stops by a strong spring action, as in the device abovedescribed. To lessen this danger, I have produced a modified structure,which, while embodying the general features of my said casing, isprovided with a sliding lip or finger for pressing the blade into placewhich has no tendency to force the blade forward suddenly, but whichwill hold it firmly when in place.

In the drawings, 23 represents the sliding' lip having the upturnedportion 24 for engagement with the back of the blade. It slides back andforth in a recess or cavity 25, formed in the top of the blade-support,and has a depending portion 26, moving between the prongs 27 of the bentarm of the spring 1l. These prongs normally press upward against theunder surface of the recess within which the bladeholding lip moves, andthus forcing it against the under surface of the recess serve to holdthe lip securely in any desired position. As in the first form of myinvention,when moved back for the insertion of the blade the lip slidesover and bears down upon the elevation l0 of the cross-arm '9, therebydepressing it and raising the clips for the insertion of the blade.After the blade is inserted the lip is pushed forward, thereby releasingthe clips and permitting them to press down upon the blade,while theback of the ylip is moved up to engage against the back of the blade.The tension of the spring-arm 27 causes sufficient friction to retainthe lip in the adjusted position and hold it firmly against movement.

In making safety-razor blades the grinding is usually done by hand, andit is almost impossible to grind them uniformly, no two blades everbeing of exactly the same bevel or pitch. It thus happens that very fewblades will fit accurately upon any given casing, there often being someslight tipping because of the prominence of one supporting portion overanother. This impairs the rigidity and firmness of the device, and inorder to obviate this difficulty I have devisedv a structure wherein theblade-support is provided with three points of contact upon which theblade is held or supported when in position. These points of contact arethe two front portions of the support just back of the studs 22.whichsupport theends of the edge of the blade, and

a third point of contact, which I have placed at the center near theback of the blade-support, utilizing the upper rounded face or surface28 of the recess or box 25, which is raised slightly higher than thesides of the rear of the blade-holder, as will be seen in dotted linesin Figs. 9 and 15.

In Fig. 15 a section of the upper face or surface 28 of the box 25 isshown and a p0rtion of a blade in contact therewith. It will readily beseen that the rear support for thel blade having no appreciable surfaceaffords no opportunity for the blade to tip, and it is therefore heldrigidly in place by the retaining-clips. As is well known, by means of athree-point contact it is possible to secure a firm support forirregular shapes of all kinds, and by this means, no matter howirregularly the blade may have been ground, it is supported firmly uponthe blade-support and by means of the fastening devices clamped securelyin that position. It will be readily understood that other means may bedevised for providing a blade-support which will receive and hold firmlythereon blades of varying bevel or pitch and that the blade-support maybe supplied with three points of contact for the blade in many otherways than the specific one shown, and I do not limit myself as to this.It is furthermore obvious that many other modifications and changes maybe made without departing from the spirit of my invention, and I do notlimit myself to the particular forms shown and described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-.
